abs'ingiand. lacamaking machines by temporary stopping off the bobbinsin their tracks or at V -'th'epo1nts intersection or crossing of the gsame is wel. nown. T

' 1 Ii -order to cause the arrested bobbin to 5 115?again}pass into thetrack in front of the drivers, slides are used which cause the bobbinto: move from the position of rest until it iaplaced at such a point inthe track that it is 7 withinrange of the bobbin drivers.

This, invention" relates to a device for effecting'the stop ing at theoints of inter, section'in a simp e and reliab e manner. To that endtheplates or trays are oval, that is to say longer ln the direc tion of thewheel cir 25. 016, than in their direction of width, and the drivers ofthe bobbins are of such length that they leave the" driver pin of thebobbin when the latter has arrived at the center in front of 1 the'ointof intersection or crossing of thetrac so thatthe bobbin stops herein front of two spring stopping devices or holders reaching into thepoint of'intersection, while it isagain rendered. operative by a slidedriven by the pattern gear which forces the bobbin between the twospring holders into the track to such an extent that it arrives ain' infront of the driver. 'As

widene portions or recesses in the tracks or atthe points ofintersection are avoided, the bobbinzhas everywhere a positive uidanceand is always stop ed again at t e same. point atthe place 0' stopping.As further, the attern gear has no connection with the bob in stop ingdevices, but only affects the advance of t e bobbin slides, the machine,in addition to being made to work in a reliable manner, can beconsiderably simplified and ch'eapened.

In theifdrawings, Figure 1 shows'in plan a, portion of the trackupperplate of the machine, Fig. 2 is a cross-section on line A'B of Fig. 1,and Fig. 3 is a plan in section on line 1 Gel) of Fig. 2. Figs. '4and'5'are respectively plan and oross-seotionuof a modified constructionof the bobbinstopping device.

Fig. 6 shows a bobbin slideand switch-mo tion in plan, on a portion ofthe machine, the upper plate bein i shown dotted, and the parts arrangedun er the bottom plate of theniachine, beingalsoshowndotted. Figs. 7 0b;

and 8 are also plans with the driving devices-s in different ositions.Fig. is a cross-se tion'on line --F of Fig. 6. j Y I The trays a arelarger in the direction oft ',the wheel-circle than in width, and thebob- 5;;-

bin drivers I) are of such length that they carry with them the bobbininto the tracks. having the 'shape'corresponding to that ofaw the trays,only up to the center in front of the crossing, and then pass the bobbinpint Be-" 7a; tween the drivers of two adjoin' 'wheels there is,therefore, a distance whic isa proximately equal to the thickness oft eobbin driving pin. Underthe drivers are I mounted on suitable supports 0spring, holders dwhich face each other withstheir' free ends and form.an inlet angle for the driving pin. f of the bobbin g. The drivers bbring the bobbins up to the angle formed .by

the -holder springs and then pass the bob-- .bin pin. In that positionthe bobbin can, therefore, be stop ed for any desired length: of time. 7At each point of intersection on crossing, are mounted; opposite theswitches h arranged and moved i: well known manner, that is to sayalternately on the inner and outer side of the wheel-circle, slides'iwhich 'are advanced by the patterngear, and push the bobbin whichstopped in front of the holders d, with its front end into the track infront of the drivers. This position of slidesand bobbins is shown inFig. 1 at 'i, and-f According to the position 0 the switch, the advancedbobbin is brought to the right or to the left into the track and thuscaused to f Work. The slide '1', is controlled by a s ring 7c whichbrings it back again after eac ad: vance by the pattern gear. Theconnection! of the slige to the pattern gear can be effect ed in dierent ways. illustrated Fig. 2, a bell crank lever m ensgages behind aprojection n of the slide i,- against which also presses the spring 70.The other arm of the lever m is connected to'a; second bell crank lever0 arranged under the 105 machine and driven by means of the connect ingrod p by the pattern gear. I

As the springs d have often to be repaired owing to the wearing out, andare easily broken they can be replaced by a bobbin In the constructionproximately at such point.

holder w is co cted to the advance slide and the free end of which,engaging behind;thebobbin pin, is moved, during thei' advance of theslide to such an extent beyond the crossing of the tracks that theadvanced. bobbin can'pass the end of the p To the slide i driven by thepatterngear,

is secured the bobbin holder or stopping device l igs. 4' and 5 the freeend 1" of which is, bent slightly upwards this end, when the slide ispushed back being'situated beneath;

, ,The return of the slide i is effected, like in the precedingconstruction, by a spring 7c.

At the upper part of Fig. 4,'the slides iandholders 1 r, are shown in'that position in which the bobbin, left by the drivers Z) but stilladvancing owing to its momentum is held up and stopped by the holder r,.The bottom part of Fig. 4 shows, on the contrary,the slide '5, withtheholder r 7-, in advanced position, and it will be seen that in thiscase the holder has passed so far beyond the crossing of the tracks thatthe bobbin pin f can freely pass.

In order to guide the bobbin g which has been advanced and carried alongby the drivers, either back to the plate from whence it comes or furtheron to the adjoining plate, the switches h are moved to and fro betweenthe plates in well known manner. For this continuous uniform'oscillationof the switches, there are several wellknown, more or lesscomplicated, driving devices for which a comparatively large consumptionof power is required. The parts are also liable to great wear, so thatit is frequently necessary to repair the machine or to replace theparts. These drawbacks are greatly reduced by the arrangement shown inFigs. 6 and 9. These arrangements are characterized'l by thesimultaneous movement of the slides/which advance the bobbins and theswitches by? means of. a system of levers actuated by the pattern orjacquard gear: 2 by the fact that two levers are provided'for movingeach slide, each of said levers being separately connected with thejacquard gear. -'Each slide is advanced, simultaneousl with one of theslides next thereto but on t e opposite side of the track, owing to thepull of the jacquard gear. Owing to this :combined switch andslidemotion, only those switches are moved in which a change of position isrefholder or e produced,, all other switches remaining in" thepositionof rest. -The airrount of power consumed is therefore smaller,and the wear of the machine is reduced.

This method of coupling and connection to the patterngear results in each slide being advanced either together. with theopposite adjoining s lideto the left, or with the adjoining slide to theright, according asthe pressure" levers 1) or w are partly turned by thepattern ear. I f I o The switches h are controlled by springs in suchmanner that they all press against the same side of the trays a, sothat, as shown in Fig. 6, the correspondin track is uite open in onedirection of trave of the b0 bins, and

N hen the bobbins travelasshown in Fig. 7, in which,

case the threadwof the bobbins rotating in pairs on the trayscontinuously produce a braiding strand, it is merely necessary to movethe outer switches h, since the track for the bobbins f 7"; f, is open.These outer switches are moved by means of the pressure levers 1) by theconnection 1 y, 31,. The inner switches= which are move by means of thepressure levers w by the connection w 66 43 utilize the open track andthe movement of the inner switches takes place owing to the advance ofthe slides by the pressure levers. -w. The outer swit hes and thepressure lever was well as all the levers and the rods, remain thereforein the position of rest. Owing to the last mci'zi'ionel mutual passageof the bobbins, thvir threads form in well the hand bobbin lace isproduced.

known manner the connections between the single strands, and a ineshworkpeculiar to It will be seen that in this arrangement always only aportion of the switches is moved, so-that the economy of power is thegreater, the reater the numberof trays of the machine. t will be alsoseen that owing to the temporary stopping of the switches and of theparts moving them, the wear is reduced.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. A braiding and lace making machinecomprising crossin tracksand bobbin drivers, bobbins wit pins, trays ofgreater imension in the direction of the wheel circle than in that ofthe width, spring holders for the bpbbin pins constituting an inletguide and arranged at each crossing to act as a bobbin stopping device,slides independent of one another for moving the bobbins free from theholders into reach of the drivers, and pattern gears for controlling theslides.

2. A braiding and lace making machine comprising crossing tracks andbobbin drivers, bobbins with pins, trays of reater dimension in thedirection of the whedi circle than in that of the width, spring holdersfor the bobbin pins constituting an inlet guide and arranged at eachcrossing to act as a bobbin stopping device, slides independent of oneanother for moving the bobbins, pattern gears controlling the slides andbobbin stopping devices secured to the slides.
